When Veronica says she'll go to Parker's party "if [she] must" and Mac replies "you must, you must!", this is a reference to the lines spoken by Gene Wilder (Jim) and Cleavon Little (Bart), in the 1974 movie Blazing Saddles (1974).
When confronting dumbfounded juvenile delinquents with a paint ball gun Veronica channels Jules Winnfield from Pulp Fiction (1994), repeating his remark to a likewise dumbfounded Brett: "Say 'what' again. I dare you. I double dare you!" Of course Veronica does not recite the maternal-expletive at the end of Jules' original speech.
